Abstract

The influence of the growth parameters on the concentration gradient of Pb1−xSnxTe monocrystals grown by the vertical Bridgman technique is described. The concentration profiles of all three constituents (Pb, Sn, Te) have been analysed in ingots having different Pb-Sn ratios and grown under different conditions. The presumed role played by free convection in the Pb-Sn ratio is shown. Te was found to be constant in all ingots and not dependent upon the growth conditions.
